Abstract
Chia seeds (Salvia hispanica L.) are small seeds that develop on an annual herbaceous plant. Recently, there has been tremendous growth in the use of chia seeds because of their associated medicinal as well as high nutritional values. Initially, chia cultivation took place in Mesopotamian cultures, eventually disappearing for some centuries before being rediscovered in the mid-20th Century. In this paper, the main aim has been to provide an overview of chia seed in relation to its perceived medicinal properties. From the majority of scholarly affirmations, it has been established that some of the compounds that chia seeds contain, explain its associated healthful effects include minerals, vitamins, proteins, dietary fiber, polyunsaturated fatty acids, and ω-3 fatty acids. Also, the literature contends that chia seeds are excellent sources of antioxidants and polyphenols, which include quercetin, myricetin, rosmarinic acid, and caffeic acid. Around the world, therefore, more and more scholarly investigations have focused on some of the beneficial effects of chia seeds, including the food, pharmaceutical, and medicinal industries. In this paper, it has been established that chia seeds have their medicinal properties gained in terms of pharmacological activities that include steatohepatitis and acute dyslipidemia improvement, sensory attributes, bioactive peptide and protein source, metabolic profile, and antioxidant and appetite suppressing properties. Important to note is that while most studies concur regarding these medicinal properties, in a few investigations, findings suggest that chia seeds do not pose significant beneficial effects, especially concerning health improvements in human subjects. As such, there is a need for future research to examine some of the parameters that could explain this variation, upon which more valid and informed conclusions and inferences might be made.
